IRRIGATING AND DRAINING SYSTEM.

Specification of Letters Patent.

Patented aan@ ec, lair.

Application led July 1, 1916. Serial No. 107,145.

To all whom t may concern:

Be it known that I, JOHN S'rnELQUis'r, a. citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Irrigating and Draining Systems, of which the following is a specification, reference being had to the accompanying drawings.

This invention is an irrigating and draining system.

One object of this invention is to provide a system of irrigation that will furnish a supply of water to the soil beneath the surface so that the water may readily reach the roots of plants.

Another object is to provide an interchangeable system of drainage or irrigation, which comprises a main ditch or drain with lateral ditches or drains, the change from drainage to irrigation being accomplished readily and quickly,

A further object is to provide a sump for the main drain from which the water may be readily pumped and also from which the main may loe readily supplied for irrigation.

A still further object is to more particularly provide a drainage system for lands protected by levees by forming a drainage ditch parallel thereto which is connected to the sump.

Broadly stated, the system comprises a main ditch or drain to which are angularly connected lateral ditches or drains, the main ditch or drain being connected to a sump, a pump adapted to cooperate with the sump and therefrom the several ditches or drains, and a drain ditch also connected to the sump.

One method embodying a practical form 0f the system will be described and illustrated in the accompanying drawings, in which,

Figure l isa plan view of the system;

Fig. 2 is a view partly in section and partly in elevation illustrating the system as herein embodied.

The main drain 5 may be constructed of tiling or pipe, as is desired.. Preferably spaced on opposite sides of this dra1n5, are

' suitable openings to which are connected the lateral drains 6 and 7. These lateral drains may be formed of pipe or tiling, as is desired. As shown more particularly in Fig. 1, these laterals are angularly connected to the main 5 and are seventeen in number.

This is purely an arbitrary number as any desired number may be used, whether it be two or three or twenty or thirty.

Adjacent one end of the main drain 5, there is a sump 8 which has its bottom placed considerably below the line of the main drain 5. The end of this main drain 5 is provided with a suitable outlet which extends downward and terminates near the bottom of the sump 8.

The sump 8 may be formed of any convenient material and is preferably of such size as will supply an adequate amount of water to the main drain 5 when it is desired to use the water for irrigating the soil beneath the surface.

When the lateral drains 6 and 7 are utilized for the purpose of drainage, they convey the water to the main drain 5 and from there to the sump 8. The sump 8 has projecting into it suitable piping 9 which may be either the suction or discharge end of the valveless pump 10. Connected also to this pump 10 is another line of piping 1l which may operate also as suction or discharge. The end of this piping ll, as shown in both of the figures is adapted to extend below the surface of the stream l2. As shown morepparticularly in Fig. 2, this piping ll extends across alevee 18 and the pump l0 is preferably positioned upon the land side of such levee.

This pump l0 is adapted to withdraw or empty the contents of the sum 8 when the piping 9 is utilized as the suction end and the water is then discharged through the piping ll into the stream 12.

By utilizing or employing a number of these main drains 5, their laterals 6 and 7 and the sumps 8, a large area of land may be drained or irrigated, as is desired. These main drains 5 and their sumps 8 should be spaced a sutlicient distance so that either drainage or irrigation may be more effectually accomplished.

Having thus described this invention, what is claimed is l. A system of the class described comprising a main pipe, lateral pipes connected thereto, a sump with which the main pipe is in communication, a pipe leading from a source of supply and terminating adjacent the bottom of the sump, a pump interposed in said last named pipe, a drainage ditch, and a pipe in communication with said drainage ditch and the sump.

thereto, a sump wlth which the main pipe 1s 1n communlcatlon, n plpe leadlng lom a source of supply and terminating adjacent the bottom of the sump, L pump interposed 1n sald last named plpe, a dramage dltch, a plpe 1n communlcatlon Wlth sind drinnage ditch and the sump, and :1 valve inten posed n said Inst named pipe.

In testimony whereof I hereunto aHX my signature in the Vpresence of two Witnesses.
